C validating numeric input

In this article we have shared two C programs to check if the input number is palindrome or not.

In computer science, data validation is the process of ensuring that a program operates on clean, correct and useful data.

A static analysis tool might allow the user to specify which application-specific methods or functions perform input validation; the tool might also have built-in knowledge of validation frameworks such as Struts.

The tool may then suppress or de-prioritize any associated warnings.

This will lead to parts of the system receiving unintended input, which may result in altered control flow, arbitrary control of a The "input validation" term is extremely common, but it is used in many different ways.

Therefore, data validation should start with business process definition and set of business rules within this process.

Rules can be collected through the requirements capture exercise.

Input Validation should not be used as the primary method of preventing XSS, SQL Injection and other attacks which are covered in respective cheat sheets but can significantly contribute to reducing their impact if implemented properly.

Input validation should be applied on both syntactical and semantic level.
